Abstract

An LED replacement light source for typical flash lamp projector bulbs. The LED source can be configured in the same form factor as the original bulb module. Clusters of LEDs or LEDs in series and parallel can be used to replace the projector lamp module. A varistor or other surge protector can be used to protect the LED array from the initial high voltage firing spike supplied by the power supply. The replacement module can have LEDs mounted on a heat sink with a collimator in front of the LEDs and an optional reflector.
